Solvents are generally used for treating soils that would otherwise require too much time, force and heat for the customer to remove. To the end user, this activity is a necessity on which they hate to spend time, money and effort.

Crop disease and reduced OJ consumption behavior have triggered sustained supply reductions and price increases the coming decade, while terpene solvent demand increases.

I don't understand how reducing OJ consumption will lead to reduced supply...


Elevance Clean™ 1000The Advantage of d-Limonene Independence

9

Elevance Clean™ 1000 is a high-performing, bio-based ester that easily formulates with d-limonene to mitigate price stability and security of supply problems in tar/asphalt removal and degreasing products.

Protects profitability by insulating from supply shortages

Protects profitability by insulating from d-limonene price instability

Boosts product performance while maintaining citrus aesthetic

Assimilates well in existing dL formulations; similar HLB requirement.

10

Elevance Clean™ 1000 creates cost advantages for your d-limonene cleaners, provides insulation from citrus supply/price fluctuations, while enabling measurable degreasing improvements.

Elevance Clean™ 1000Motor Oil & Lithium Grease

11

Elevance Clean™ 1000 is more effective in the removal of tenacious, persistent grease than d-limonene, and soy methyl ester (a common dL extender candidate) in immersion cleaning.
